OF ILION, NEW YOBK,A' COBiPORATION OF NEW YORK CORNER JOINT FOR CABINETS OR THE LIKE Application flledzoctober 7,1880. Serial No. 486,842.

Thisinvention relates to display cabinets, museum cases or the like having sides or panels mounted in interfitting marginal'frames, and pertains more particularly to improvements in the corner oints of museum cases of the type illustrated and described in'my copending application, Serial No. 397,520, filed October 5, 1929, which has resulted in Patent No. 1,859,798, dated May 24, 1932.

The principal object of my present invention is to provide an improved corner joint having closely interfitting frame members which have complemental faces provided with packing material arranged effectually to prevent the entrance of dust or vermin through the joint and which may be readily interconnected without damaging or displac ing the packing and without injuring their interfitting elements.

A recommended embodiment of the invention is illustrated in the accompanying drawing which shows a transverse section through a typical corner joint of my improvedcabinet.

The interfitting frame members 1 and 2 of the particular embodiment chosen for the purpose of illustration may constitute the interlocked uprights at a vertical corner of a museum case or the like, and have the general characteristics of the frames or margin pieces more particularly described and claimed in my said application. The respective members have longitudinal channels 12 and 13 receiving the edges of side panels 3 and 4 which may be of glass or other suitable material and which may be secured in the channels by means of packing strips 11. It

will be understood that the panels may be mounted in a rectangular frame composed of connected members similar to the marginal pieces 1 or 2, and that the assembled units may then be erected and interlocked at the corner joints as hereinafter described.

Frame member 2 has a longitudinal tenon 5 received and closely fitting within a complemental channel 6 provided in the adjoining member 1, and the inner side of member 2 abuts a flange or shoulder 7 forming part of member 1. The flange 7 has a longitudinal recess or groove 8 which receives a packing 9 of asbestos yarn or other suitable material,

and the opposed face offrame member 2 is cut away to'provide an inclined surface 10.

When'the frame members are being assem "bled,sai'd inclined surface tends to wedge and compress the packing 9 betweensaid mem bers and to prevent tearing, pinching or undue displacement of the packing material.

The inner face oftenon 5 also has a groove -16 receiving packing 17 which is compressed between saidface'and the bottom of the channel 6 when the frame members are joined together, and it will be observed that the packing 17, as well as the packing 9, not only fills its groove but spreads outwardly over the grooved face under pressure. Hence the packings may be generallyround in cross-section and may be secured in their respective grooves; as by a suitable adhesive, before the frame members are connected.

By utilizing the aforesaid construction, an

adequately thick packing may be employed surfaces which are separated from each other by intervening meeting faces disposed at an angle to each other, the progress of foreign matter through the joint is further impeded.

.The frame members 1 and 2 may be made of any suitable rigid material, but the use of metal affords a nicer fitting therebetween and also furnishes a narrow corner upright for a cabinet having glass panels; for this urpose I prefer to use extruded-metal, suc as aluminum, in order that each similar unit will be substantially identical in cross-sec-- tional dimensions.

It should be understood that the present disclosure is for the urpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the appended claims.

I claim:

1. A pair of frame members constituting the corner joint of a cabinet or the like, one of the members having a channel and a flange spaced therefrom and the other memher having a tenon fitting within the channel and a surface opposed to the face of said flange, the flange having a longitudinal groove for the reception of packing, and packing material between the tenon and its channel and between the flange groove and said surface.

2. A pair of frame members constituting the corner joint of a cabinet or the like, one of the members having a channel and a flange spaced therefrom and the other member having a tenon fitting within the channel and an inclined surface opposed to the face of said flange, the flange having a longitudinal groovefor the reception of packing, and packing material between the tenon and its channel and between the flange groove and said inclined surface, said surface wedging the packing between the frame members and tending to prevent tearing of the packing when the members are being assembled.

3. A pair of frame members constituting the corner joint'of a cabinet or the like, one of the members having a channel and a flange spaced therefrom, and the other member having a tenon fitting within the channel and a surface opposed to the-face of said flange, the tenon having a longitudinal groove for the reception of packing and the flange having a similar groove, and packing material disposed within the respective grooves and compressed between the opposed faces of the members.

4. A pair of frame members constituting the corner joint of a cabinet or the like, one of the members having a channel and a flange spaced therefrom, and the other member having a tenon fitting Within the channel and a surface opposed to the face of said flange, the tenon having a longitudinal oove for the reception of packing and the ange having a similar groove, and packing material disposed within the respective grooves and compressed between the opposed faces of the members adjacent the grooves, the surface of the second member having a longitudinal recess opposing the flange groove and receiving the packing carried in said groove when the members are fitted together.

5. A pair of frame members constituting the corner joint of a cabinet or the like, one of the members having a channel and a flange spaced therefrom, and the other member having a tenon fitting Within the channel and a surface opposed to the face of said flange the tenon having a longitudinal groove for the reception of packing and the flange having a similar groove, and packing material disposed within the respectivegrooves and compressed between the opposed faces of the members adjacent the grooves, the said surface of the second member being inclined away from the flange to provide a longitudinal recess opposing the flange groove and tending to wedge the packing between the assembled members.

6. A pair of frame members constituting the corner 'oint of a cabinet or the like, one of the mem ers having a channel and a flange spaced therefrom, and the other member having a tenon fitting within the channel and a
